Description

The HISPEC-DESPEC collaboration aims at studying the evolution of the shell structure and
exotic nuclear shapes in uncharted nuclear territory, providing spectroscopic information for the
nucleosynthesis of medium to heavy nuclei, exploiting the uniqueness of the GSI-FAIR laboratory.
In this first years after the restart of GSI, starting from early commissioning in 2019 to real
experiments in 2020-2022, the collaboration focused on stopped-beams experiments, with the aim
of providing a complete picture of the  -decay process [1,2]. The use of the FATIMA array coupled
to HPGe detectors provides, in fact, a detailed reconstruction of the decay scheme with a particular
focus on specific observables, such as levels lifetimes.
In this contribution a detailed description of the detection equipment and first results of the
campaigns, together with an outlook onto the future experimental program will be given.
